BARREL-TAP.

SPECIFICATION forming part of Letters Patent No. 234,877, dated November 9, 1880, Application led June 8, 1880. (No model.)

To all whom it may concern:

Be it known that we, ZENAS FETTERLY and Osons DUr'roN, ofthe city and county of Yolo, in the State of California, have invented an Improved Barrel-Tap; and we do hereby declare that the following is a full, clear and cxact description thereof, reference being had to the accompanying drawings.

Our invention has reference to that class of devices for drawing liquids Jfrom barrels and caslrs in which a tap-plug is permanently secured in the barrel-head, so that by securing a draw-pipe in a hole prepared for the. purpose in the plug and turning a spigot in the tap by means ot a key the liquid is drawn through the pipe.

Our invention relates to the construction of the tap and spigot; and it consists of a simple arrangement by which we secure a perfectly tight joint through which leakage is impossible, and which will remain tight as long as the tap lasts.

It also relates to an attachment for cleaning the inner end of the hollow spigot every time the spigot is turned, which is especially useful when the tap is used in beer-barrels that are pitched after being used.

Referring to the accompanying drawings, Figure l is a perspective View with a side partly broken away. Fig. 2 is a longitudinal section through the outer shell or plug. Fig. 3 is an end View taken from the left-hand side of Fig. 2. Fig. 4 is a view taken from the right-hand side of Fig. 2. Fig. 5 shows details ofthe hollow conical spigot. Fig. G is a longitudinal section through the outer shell, with the conical spigot removed.

LetAreprcsent ahollow tapering metal plug or shell, the outer or large end of which is enlarged or tlan ged so as to form a head, b, while the exterior ot' the tapering portion is provided with screw-threads, so that it can be screwed into a hole in the head ofthe barrel until the under side ot the ilanged portion or head b ts down against the outside of the barrel-head, leaving the small end ot` the plug to project inside of the barrel. We shall usually make the tapering threaded portion of the plug large enough to iit in the ordinary bung-hole in the head of the barrel; but this is simply a convenience and is not necessary, as it can be made of any desired size and a special hole bored for it.

A hole, 7L, is made in the outer end of the plug on one side of the central hole, in which the spigot tits and operates, and this hole is either made angular or is curved, so as to connect with the interior bore of the plug. The outer portion of this hole is tapped with screwthreads, so that one end of a bent pipe, K, can be screwed into it for drawing the liquid through.

The interior bore ot' the plug is tapering, being largest at the inner or small end and smallest at the outer end. In this tapering bore we place the hollow tapering core or spigot O, which is ground to t the taper of the bore, so as to form a joint that will keep tight as it wears. The lower end of this hollow core or spigot is covered by a plate which is perforated, so that the liquid can pass to the interior of the spigot. The outer end of the spigot has a square or other shaped recess, S, in it, into which a key, T, will tit, in order to turn the spigot when desired.

A transverse slot, c, is made on each side ot the spigot O, and a sc1cw-bolt-,f,passes through the plug and through the slots in the spigot, so that the spigot can be turned either way as far as the slots and screw-bolt will permit.

- A hole, g, is also made through the side of the hollow spigot in the same plane with the opening of the passage h in the plug, so that when the spigot is turned in one direction as far as the screw-boltf and slots will permit the two holes are brought opposite each other, and the liquid can pass from the hollow spigot ont through the hole h and bent pipe K, but when the spigot is turned in the opposite direction the hole g is thrown out ot" line with the passage 7L and the tlow of liquid is cut off.

A bolt, l, is arranged in the wall of the bore near the outer end ot' the plug, so as to be thrown outward by a spring and ente-r a recess or socket, u, in the spigot when the spigot is turned off, and thus lock it in place.

A slot, O, is made from the outer end ofthe spigot down in a line across the recess or opening a, and a wed ge-plate, V, is secured on one side of the key T, so as to pass down ICO through this slot when the key is inserted into the outer end of the spigot and press the bolt l back out of the recess, and thus unlock the spigot and allow it to turn.

This forms a simple and effective faucet or permanent tap for beer and other barrels in which a liquid is contained under pressure. The conical spigot ts lengthwise in the shell, so that the pressure inside of the barrel keeps the joint tight and prevents leakage. The device is cheaply constructed and durable, as the liquid-passage h is bored directly through the outer shell.

When not in use the key T is withdrawn and the draw-pipe K removed, so that nothing projects from the end of the barrel except the shallow head b. The removal of the key permits the bolt Z to enter the recess or socket u and lock the spigot in position.

In order to keep the inside end of the spigot clear, we secure a knife or scraper, X, across the inner end of the plug or shell A, so that when the spigot is turned to let on the liquid the edge of the knife or scraper will clear the perforations or holes in the end plate, through which the liquid passes to enter the spigot. This knife or scraper is held in place by a transverse bar, Y, and screw Z. The end of the shell has an opening cut in each side opposite each other, and a groove, a, is made around it on the inside, so that the ends ofthe bar can drop through the openings and be turned into the groove. The screw Z passes through its middleand bears against the middle of the knife or scraper, so that by turning the screw against the back of the scraper the pressure of the scraper against the perforated plate can be regulated. This provides an antomatic cleaner that will keep the perforations clear, and is especially useful in beer-barrels that are pitched after using.

Having thus described our invention, what we claim, and desire to secure by Letters Patent, is

1. An improved tapping device for barrels and casks containing liquid, consisting ofthe tapering eXteriorly-threaded plug or shell A, having` the head b, bore or hole 7L, draw-pipe K, and push-pin l, and provided with a smooth tapering bore, in combination with the hollow tapering spigot C, having the holeg in its side and key-hole a in its outer end, said spigot being secured in the hollow shell A by means of the opposite transverse slots c and screwbolt j', combined and arranged substantially as described.

2. In a barrel-tapping device having a rotary spigot operated by a removable key, the recess or socket u in the spigot and the bolt Z in the plug or shell, in combination with the slot O in the outer end of the spigot and the wedge-plate V on the key, substantially as and for the purpose specified.

In a barrel-tapping device having a rotary hollow spigot, into which the liquid is admitted through a perforated end, the stationary knife orscraperX, for the purpose specified.

In witness whereof we have hereunto set our hands and seals.
